Use ScraperWiki to Help Turn Web Pages Into Usable Data

With scraping you create programs that reads and organize web pages. For example to get your bank account data into a spreadsheet. (There are still banks that doesn't help you to do that!)

A post from Lifehacker by Dave Drager has the whole story. Here is a part:

 

A scraper is a program written to take content off of a webpage or other data source and turn it into some kind of usable format, usually an RSS feed or by entering it directly into a database. Designing a scraper can be tricky as each site is different,ScraperWiki aims to fix this by creating a repository of these scripts with a goal to ease the pain of designing them.
An example use of a scraper: let's say a government entity releases daily information regarding finances, and you want to graph or otherwise track this data for personal or business use. Going to the website each day and entering the data manually is certainly one labor-intensive way to do it, but as with any good hacker will tell you - if you have to do anything more than once it is better to automate it.
